ROTARY MOTOR.

Specification of Letters Patent.

Application filed. January 1,6, 1911'. Serial N o. 602,786.

To all whom it may concern Be it known that I, ELMER E. HAUER, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Rotary Motors, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relatesto rotary motors and.

more particularly to rotary motors employed in driving boiler tube cleaners that are adapted to travel through the tube with the cleaner, although they may be used for other purposes.

The object of my invention is to simplify and `improve the construction so as to give greater efficiency and to afford better means of lubrication.

With these and other objects in view my invention consists of the constructions and combinations hereinafter described and set forth in the claims.

In the drawingsFigure 1 is a longitudinal section of a rotary motor, taken through the exhaust ports, embodying my invention. Fig. 2 is a longitudinal section taken through the inlet ports. Fig. 3 is cross-see tion on the line A A of Fig. 1. Fig. 4 is cross-section on the line B B of-F ig. 2 and Fig. 5 is cross-section on the line C C of Fig. 1.

Like numerals represent the same parts in the several views.

In the drawings 1 represents a casing having a head 2, preferably rformed integrally therewith as shown and having exhaust ports 3. sleeve 4 and a wearing plate 5 having exhaust ports 5a is interposed between said sleeve and exhaust head, a dowel pin 6 holding said sleeve and plate from turning in the casing. A journal block 7 is seated against the opposite end of said sleeve and a dowel pin 8 keeps the same from turning in the casing. Said sleeve is formed with exhaust recesses 9 adapted to register with the exhaust ports 5a of the Wearing plate; and is further provided with inlet recesses 10 adapted to register with inlet ports 11 in the journal block 7.

A head 12 is screw-threaded at 13 to the casing and has a reduced portion 14 which bears against the journal block and forms with said journal block and casing an annu- `in the casing.

yand al sprin Said casing is provided with aY lar chamber 15 into which the `inlet ports 11 of the journal block open in whatever position to `which'zthe head 12 may be turned Said head extends rearwardly and is made hollow as shown so that when screw-threaded in place it forms with said journal block a lubricant chamber 16. Inwardly extending ribs 17 formed on the walls of the head 12 have inlet ports 18 therethrough leading from a screw-threaded opening 19 in which the supply hose isI attached, to the annular chamber 15. A feed hole 20 to supply the lubricant chamber is providedwith a hollow plug21, a ball 22 23 to hold said ball `in the opening of the plug.

A rotary piston 24 is preferably formed integrally with a shaft 25 which is journaled in the block 7 and head 2, bushings 26 and 27 being preferably provided to form bearings therefor. Theforward end of the shaft projects through the head2 and is screw-threaded at 28 to attach the tool to be driven. The sleeve 4 forms a yworking chamber of such dimensions that positely disposed crescentshaped chambersv 29 as particularly shown in Fig. 5.. .Paddles 30 are seated in recesses 31 of the piston and are adapted to move radially into the chambers 29 in a well known manner.

A feed conduit 33 leads from the lubricant chamber 16 to the working chamber and I preferably also provide a cross conduit 34 opening through the bushing 26 yto rear journal bearing; and the quantity of lubricant is adjusted by the means of the needle valve 35 seated at the junction of the conduits as shown and operated by a screw-plug 36 to which it is attached.

An annular recess in the head 2 abutting the bushing 27 forms a lubricant chamber 37 having openings 38 to the front journal bearing; and a conduit 39 leads from the working chamber to said lubricant chamber 37. v It will be seen that the rear bearing and. the working chamber are supplied with the desired amount of lubricant; and that the lubricant being mixed with the motive agent also passes to the front bearing.

To relieve the pressure of the motive agent at the rear end of the shaft a conduit 40 is provided extending throughA the piston and Patented Jury "z, i914.v

shaft, venting through at the end thereof or' Y at the side as shown or in any suitable n manner. y y y lI. preferably provide a removable cap 32 at the rear end of the journal block 7 so that the lbushing 26, when it becomes worn may y sion, the circumferential walls of which have inwardly projecting ,ribs with ini-et ports v therethrough for the motive agent, l substan-k be readilyfremoved and a new bushing .supplied. j

Having thus described my invention I claim l; In a rotary motor, a casing and a head therefor havingl av hollow *rearward eXtentially asdescribed. Y

2. In a'rotary motor, acasing, y block lseated therein and a head forfsaid casing having a hollow rearward extension closed at itsoouter end, the circumferential walls of which form with saidclosed end and said block av lubricating chambensaid circumferential walls having inwardly pro-y jecting ribs with inlet ports therethrough for the motive agent,- substantially asl described. r

3. Inv a rotary motor,` a casing having a working chamber, a journal block lseated in said casing and having portscommunicating with said working chamber, al head screw threadedto said casing and having a reduced portion of vless diameter'thanthe bore of the lcasing,seated against said block and forming with said block and casing an annular chamber into which said ports open,'

said head yhaving a hollow rearward eXtension, closed at its outer end, thel circumferential walls of which have inwardly proj e'ct ingribs with inlet ports therethrough to said annular chamber, substantially as described.

4l. ln a rotary motor, a casing having a bearing closedl at one end and a piston hav-v ing a shaft journaled in said bearing, said shaft having a conduit with a free vent opening to the atmosphere to relieve" the pressure at the end ofthe shaftin said bearing, substantially as described.

a journal 5. In a rotary motor, a casing having oppositely disposed inlet anddischarge ends, athroughbearing insaid discharge end and a socket 'bearing in said inlet end, a piston yhz'iving ia shaft journaled in saidbearings andprojecting through said discharge end, said shafthaving a conduit with'a free vent vopening tothe atmosphere to relieve the pressure attherear V'end of said shaft, substantially as described.

y 6. In a rotary motor, a casing having al motorfchamber with oppositely disposed `inlet and discharge ends, 'bearings in the respective ends, the bearing at the inlet end being closed except an opening into 'the .motor chamber to `receive the motor shaft, a piston with radially moving blades in said "chamber and having a shaft,journaled` in said bearings, said shaft having a conduit `with a free ventfto the atmosphereto'relieve the pressure atA the rear end of said shaft,l

substantially as described.

1,] Ina rotaryv motor, a casinghaving a motor chamber, av head having a hollow 'eX- tension,y front'and rear bearings'on opposite sides lofsaid chamber, the rear bearing being closed 'at its rearv end and projecting linto said headfextens'ion, a piston having'a shaft vprojecting through said front bearing and adapted to attach the tool tobe driven, the

rear end'of said shaft terminating within'v said rear. bearing and having a conduit therein giving a free vent from said bearing to the atmosphere in front'of the motor, the circumferential'walls of said head extension having inv'vardlyextending ribs with ports theret'lnough communicating with' said Inofy Copies o'f this patent may be obtained for five ent's each, by addressing-.the Commissioner of Patents,`
